*To all whom it mayconcern: i

Be it known that I, CARL Summit, a citizen of the United States of America, re-

siding at Chicago, in thecounty of Cook and State of Illinois, have invented new and useful Improvements in" Automobile Tire Pumps, of wliichjthe following isa specifi cation. v j,

The object of the invention is to provide a simple, inexpensive and eflicient apparatus which may be mounted in a fixed andsuitable position upon an automobile running board or in like convenient relation to a vehicle of that type with operating means such as a hand lever Within convenient reach of the operator of the car, .to the end that the wheel tires may be readily inflatedfrom time to time as theoccasion may arise without the inconvenience of carrying a separate or a detachable pumpwhich when not in use must be stored within the vehicle and which in order to be of an effective size serves when thus stored to occupy space which'can be more profitably utilized in otherways; and furthermore to provide an apparatus for the urposes indicated having the maximum effiof parts of which a preferred embodiment is shown in the accompanying. drawings, it

being understood that changes in form, proportion and details may be resorted to within the scope of the appended claims without departing from the principles involved.

In the drawings Figure 1 is a side view of a pump embodying the invention arranged in the operative position upon the running board of a vehicle.

Figure 2 is a plan view of the same.

Figure 3 is a detail sectional view taken longitudinally of the cylinder.

Figure 4 is a transverse section on the plane indicated by the line 4-4 of Figure 3.

Figure 5 is a detail view showing the means of securing the cylinder bed tothe vehicle running board. r

The apparatus embodies essentially the pump cylinder 10 in which is arranged the piston 11 of which the rod 12 extends through a suitable stufling box 13 in one of the terminal heads 14 of the cylinder, a bed L AUTOMOBILE TIRE PUMP.

15 adapted to be'securedto the running board 16 of the car and serving to support and secure the cylinder a fixed position with relation tojthie running board, so as to prevent displacement or vibration thereof, and anv operating hand lever 17 fulcrumed atented'June 20, 1922.

upon a suitable bracket18 extending forwardly'from said bed frame and-operatively.

connected with the terminal cross head 19 of the piston rod.

In the construction illustrated the cylinderheads are threaded upon: the extremities of the cylinder wall with the. flangesQO of saidv heads disposed exterior lyiof the cylin- .der wall to format their inner. ends shoul-' lders 21,and in each of the cylinder heads are 'formedfinlet and outlet; port's 22and 23,"

valved to respectivelylpermit inductionland expulsion. of. air byv the movement of the piston.- As: illustrated the inlet ports are provided with' clack valves '24 while the eduction ports are fitted with spring pressed poppet valves 25, coupling nipples 26 being arranged in communication with the outlet ports to provide for the connection therewith of tubes 27, secured in place by hose clamps 28 and preferably arranged in communication witha common service tube 29, a suitable branched coupling 30 being employed to connect the I extremities of the supply tubes 27. with the service tube 29. The latter is adapted by means of a suitable cap 31 to be applied to the several tire valves to provide for the inflation of the tire tubes.

The bed 13 consists of an open'frame having side walls 31 connected by transverse end bars 32 which are spaced apart to correspond with the length of the cylinder measured to the exterior surfaces of the so i heads 14, so that when the cylinder is ar-@ ranged on the bed framethe said end bars are arranged in contact with the exterior surfaces of said heads and hold the cylinbars 32 and against transverse or radial movement by the complemental saddles and straps which combine to encircle or embrace the cylinder adjacent to the planes of the shoulders 21.. p

The bed frame is secured to the running boardbymeans of clamps 36 attachedto the side bars of the frame and provided with clamp screws 37 for engagement with the under surface of the running board.

The bracket 18 is formed by extensions of the side bars of the bed frame and consists of forwardly convergent arms .18 having upturned extremities constituting standards 38 between which the hand lever 17 is fulcrumed as at 39, and the lower extremity of the hand lever is slotted as shown at 40 v to fit over a transverse pin 41 carried'by the claimed as new and useful is 1. A tire pump for automobiles and similar vehicles having a cylinder provided with terminal heads, a bed frame for sup-porting the cylinder and provided with means for attachment to the running board of a vehicle, said frame having transverse cylinder embracing members consisting of downwardly bowed saddles in the plane of the frame and complemental straps extending over the cylinder and terminally attached to the extremities of said saddles, said frame having a forwardly extending bracket, and a piston operating lever fulcrumed upon the bracket. r

2. A tire pump for automobiles and similar vehicles having a cylinder provided with terminal heads and intermediate inwardly facing shoulders a bed frame for seating the cylinder and provided'with means for attachment to the running board of a vehicle, said bed frame having transverse bars forrespective engagement with the exterior surfaces of the cylinder heads and intermediate cylinder embracing members disposed in contact with said shoulders of the cylinder, said cylinder embracing elements consisting of downwardly bowed saddles transversely spanning and arranged in the plane of the bed frame and complemental straps extending over the cylinder and terminally secured to the extremities of said saddles, said bed frame being provided with a forwardly extending bracket, and a piston op erating lever fulcrumed upon the bracket.

In testimony whereof he afiixes his signature.
